Your main priorities are school and your sports.

• Have a plan B.  Know what your career is going to be and focus on it. 

• Make the most out of your sport while you can. Plan your future around your academics and get a good job. Have other goals in life other than sports.

• Telegraph your absences. Make sure your teachers will know when you will be gone. I can't stress this enough. You must get all the work you are going to miss because you don't want to get behind.
